Thank you Richard!

That is what I needed, I will adapt the 13b pump to the late 12a cover with a block that will have a separate 2 cycle oil source.

Hi Richard,

 

Do the injector valves vary the amount of oil injected based on load?  I

have dissassembled a pump from a 13BT and it looks to be a positive

displacement type with no apparent pressure relief function.  I do not

have any "injector valves", just plain old banjo bolts that thread into

the housings, a jet sits in the bottom of the hole below the banjo bolt.

What am I missing?

 

Thanks -- Ian

Georges,

 

the 12A pump is way to small for the 13B. According to the spec. the 12A

pump is pumping 2.0 - 2.5 cc  in 6 minutes on its two lines with the

engine running at 2000RPM.

The 13B NT does 4.5-5.5 cc on two lines in 5 minutes engine running at

2000RPM. The Turbo setting does 5.2 - 6.6 under the same condition.

One more thing, if you use the OMP. You must retain the injector valves

sitting on the rotor housing and the intake manifold. Their vacuum line is

hooked up to the intake plenum. These valves do the oil injection, the OMP

only supplies the oil!

I hope this answers the question.
